Key Operating Metrics

In Q4 FY26, we commissioned 1,035 MWs, which included 70 MWs of wind and 965 MWs of solar capacity. In FY26, we commissioned ~2.4 GWs, of which 0.6 GWs were wind, 1.7 GWs were solar and 25 MW/100 MWh of BESS. Subsequent to the end of the quarter, the Company commissioned ~247 MWs, taking the total commissioned capacity as of date to ~12.8 GWs (including 100 MW/250 MWh of BESS).

As of March 31, 2026, our total portfolio consisted of ~20 GWs (including 1.7 GW/6.2 GWh of BESS) and commissioned capacity was ~12.6 GWs (including 100 MW/250 MWh of BESS), of which ~5.6 GWs were wind, ~6.8 GWs were solar and 99 MWs were hydro. Our commissioned capacity increased by 16.6% year over year, net

of the 600 MWs of assets sold in FY26 as part of our capital recycling strategy.

Electricity Sold

Total electricity sold in Q4 FY26 was 5,189 million kWh, an increase of 3.7% over Q4 FY25. Electricity sold in Q4 FY26 from wind assets was 2,192 million kWh, an increase of 19.8% from Q4 FY25. Electricity sold in Q4 FY26 from solar assets was 2,975 million kWh, a decrease of 5.1% over Q4 FY25. Electricity sold for Q4 FY26 from hydro assets was 22 million kWh, a decrease of 45.0% over Q4 FY25.

Total electricity sold in FY26 was 24,008 million kWh, an increase of 11.3% over FY25. Electricity sold in FY26 from wind assets was 12,093 million kWh, an increase of 17.9% over FY25.

Total Income

Total Income for Q4 FY26 was INR 39,548 million (US$ 421 million), compared to INR 34,391 million (US$ 367 million) for Q4 FY25. Total income benefited from higher revenue driven by an increase in operational capacity, fair value gain on conversion of jointly controlled entity to subsidiary, higher LPS income, higher wind PLF and increase in external sales from our solar module and cell manufacturing operations, partially offset by absence of gain on sale of assets recognised in Q4 FY25 and lower solar PLF. Total Income includes finance income and fair value change in warrants of INR 1,635 million (US$ 17 million) and fair value gain on conversion of jointly controlled entity to subsidiary of INR 2,383 million (US$ 25 million).

Total Income (or total revenue) for Q4 FY26 from our solar module and cell manufacturing operations was INR 11,930 million (US$ 127 million), compared to INR 9,914 million (US$ 106 million) for Q4 FY25.

Total Income for FY26 was INR 150,635 million (US$ 1,605 million), compared to INR 109,070 million (US$ 1,162 million) for FY25. Total income benefited from higher revenue driven by an increase in operational capacity, fair value gain on conversion of jointly controlled entity to subsidiary, higher wind PLF and increase in external sales from our solar module and cell manufacturing operations, partially offset by revenue loss from sale of assets as part of our capital recycling strategy and lower solar PLF. Total Income for FY26 includes finance income and fair value change in warrants of INR 5,258 million (US$ 56 million), gain on sale of assets of INR 3,542 million (US$ 38 million) and fair value gain on conversion of jointly controlled entity to subsidiary of INR 2,383 million (US$ 25 million).

IFRS refers to International Financial Reporting Standards as issued by the International Accounting Standards Board. In addition, reconciliations of non-IFRS measures to IFRS financial measures, and operating results are included at the end of this release.

FY27 Guidance

The Company expects to complete the construction of 1.6 to 2.4 GWs by the fiscal year ending March 31, 2027 (“FY27”). The Company’s Adjusted EBITDA and Cash Flow to Equity guidance for FY27 are subject to weather and resource availability being similar to FY26. The Company anticipates continued net gains in sales of assets, which is part of ReNew’s capital recycling strategy, and has included INR 1-2 billion related to asset sales in the Adjusted EBITDA. The Company also expects external sales from our module and cell manufacturing operations and has included INR 10-12 billion of Adjusted EBITDA against such sales in this guidance.

Cash Flow

Cash generated from operating activities for Q4 FY26 was INR 19,485 million (US$ 208 million), compared to INR 19,008 million (US$ 203 million) for Q4 FY25. The increase was primarily driven by higher operating profit and lower taxes, partially offset by higher working capital deployment. Cash generated from operating activities for FY26 was INR 82,824 million (US$ 883 million), compared to INR 67,565 million (US$ 720 million) for FY25. The increase was driven primarily by higher operating profit and lower working capital deployment, partially offset by higher taxes paid.

Cash used in investing activities for Q4 FY26 was INR 27,131 million (US$ 289 million), compared to cash generated amounting to INR 7,408 million (US$ 79 million) for Q4 FY25. The increase in cash used was primarily on account of higher investment in property, plant and equipment and investment in deposits and mutual funds having maturity more than 3 months (net of redemption). Cash used in investing activities for FY26 was INR 106,537 million (US$ 1,135 million), compared to INR 74,164 million (US$ 790 million) used in FY25. The increase in cash used was primarily on account of higher investment in property, plant and equipment and investment in deposits and mutual funds having maturity more than 3 months (net of redemption), partially offset by absence of investment made in jointly controlled entities.

Cash used in financing activities for Q4 FY26 was INR 15,169 million (US$ 162 million), compared to cash used in financing activities of INR 7,492 million (US$ 80 million) in Q4 FY25. The increase in cash used was primarily on account of lower proceeds from interest-bearing loans and borrowings (net of repayments). Cash generated from financing activities for FY26 was INR 4,949 million (US$ 53 million), compared to INR 19,984 million (US$ 213 million) generated in FY25. The decrease was primarily due to lower proceeds from interest-bearing loans and borrowings (net of repayments) partially offset by proceeds from shares issued by subsidiaries.

Capital Expenditure

In Q4 FY26, we commissioned 965 MWs of solar and 70 MWs of wind projects for which our capex was INR 47,745 million (US$ 509 million).

In FY26, we commissioned ~1.7 GWs of solar, ~0.6 GWs of wind projects and 25MW/100MWh of BESS for which our capex was INR 135,576 million (US$ 1,445 million).

Liquidity Position

As of March 31, 2026, we had INR 80,629 million (US$ 859 million) of cash and cash equivalents, bank balances and investments in liquid funds. This included an aggregate of cash and cash equivalents of INR 22,845 million (US$ 243 million), bank balances other than cash and cash equivalents of INR 46,706 million (US$ 498 million), deposits with maturities of more than 12 months (forming part of other financial assets) of INR 3,792 (US$ 40 million), and investments in liquid funds amounting to INR 7,286 (US$ 78 million).

Net Debt

Net debt as of March 31, 2026, was INR 687,138 million (US$ 7,323 million). Net debt as of March 31, 2026, also includes investment from the joint venture partners for renewable energy projects in the form of convertible debentures amounting to INR 25,215 (US$ 269 million).

Receivables

Total receivables as of March 31, 2026, were INR 25,303 million (US$ 270 million), of which INR 6,882 million (US$ 73 million) was unbilled and others including receivables against external sales from our solar module and cell manufacturing operations. The Daily Sales Outstanding (“DSO”) from our Independent Power Producer ("IPP") business was 63 days as of March 31, 2026, as compared to 71 days as of March 31, 2025, an improvement of 8 days year on year.

Receivables from our solar module and cell manufacturing operations was INR 2,352 (US$ 24 million). The DSO from our manufacturing operations was 21 days as of March 31, 2026.

Cash Flow to Equity (CFe)

CFe for Q4 FY26 was INR (3,562) million [(US$ 38 million)] compared to INR (1,579) million [(US$ 17 million)] for Q4 FY25 due to higher non-cash items including fair value gain on conversion of jointly controlled entity to subsidiary of INR 2,383 million (US$ 25 million).

CFe for FY26 was INR 21,588 million (US$ 230 million) compared to INR 14,869 million (US$ 158 million) for FY25 due to higher Adjusted EBITDA partially offset by higher loan repayments and higher interest and tax paid.

Other matters

Use of Non-IFRS Financial Measures

Adjusted EBITDA

Adjusted EBITDA is a non-IFRS financial measure. We present Adjusted EBITDA as a supplemental measure of its performance. This measurement is not recognized in accordance with IFRS and should not be viewed as an alternative to IFRS measures of performance. The presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

The Company defines Adjusted EBITDA as Profit/(loss) for the period plus (a) current and deferred tax, (b) finance costs and fair value changes on derivative instruments, (c) change in fair value of warrants (if recorded as expense) (d) depreciation and amortization, (e) listing expenses, (f) share based payment and other expense related to listing, less (g) share in profit/(loss) of jointly controlled entities (h) finance income and fair value change in derivative instruments, and (i) change in fair value of warrants (if recorded as income). We believe Adjusted EBITDA is useful to investors in assessing our ongoing financial performance and provides improved comparability on a like to like basis between periods through the exclusion of certain items that management believes are not indicative of our operational profitability and that may obscure underlying business results and trends. However, this measure should not be considered in isolation or viewed as a substitute for net income or other measures of performance determined in accordance with IFRS. Moreover, Adjusted EBITDA as used herein is not necessarily comparable to other similarly titled measures of other companies due to potential inconsistencies in the methods of calculation.

Our management believes this measure is useful to compare general operating performance from period to period and to make certain related management decisions. Adjusted EBITDA is also used by securities analysts, lenders and others in their evaluation of different companies because it excludes certain items that can vary widely across different industries or among companies within the same industry. For example, interest expense can be highly dependent on our capital structure, debt levels and credit ratings. Therefore, the impact of interest expense on earnings can vary significantly among companies. In addition, the tax positions of companies can vary because of their differing abilities to take advantage of tax benefits and because of the tax policies of the various jurisdictions in which they operate. As a result, effective tax rates and tax expenses can vary considerably among companies.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under IFRS. Some of these limitations include:

Investors are encouraged to evaluate each adjustment and the reasons we consider it appropriate for supplemental analysis. For more information, please see the Reconciliations of Net loss to Adjusted EBITDA towards the end of this earnings release.

Cash Flow to Equity (CFe)

CFe is a Non-IFRS financial measure. We present CFe as a supplemental measure of our performance. This measurement is not recognized in accordance with IFRS and should not be viewed as an alternative to IFRS measures of performance. The presentation of CFe should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

We define CFe as Adjusted EBITDA add non-cash expense and finance income and fair value change in derivative, less interest expense paid, tax paid/(refund) and normalized loan repayments. Normalized loan repayments are repayment of scheduled payments as per the loan agreement. Ad Hoc payments and refinancing (including planned arrangements/borrowings in previous periods) are not included in normalized loan repayments. The definition also excludes changes in net working capital and investing activities.

We believe IFRS metrics, such as net income (loss) and cash from operating activities, do not provide the same level of visibility into the performance and prospects of our operating business as a result of the long-term capital-intensive nature of our businesses, non-cash depreciation and amortization, cash used for debt servicing as well as investments and costs related to the growth of our business.

Our business owns high-value, long-lived assets capable of generating substantial Cash Flows to Equity over time. We believe that external consumers of our financial statements, including investors and research analysts, use CFe both to assess ReNew performance and the value of the business and the platform, and as an indicator of its success in generating an attractive risk-adjusted total return. This has been a widely used metric by analysts to value our business, and hence we believe this will better help potential investors in analyzing the cash generation from our operating assets.

We have disclosed CFe for our operational assets on a consolidated basis, which is not our cash from operations on a consolidated basis. We believe CFe supplements IFRS results to provide a more complete understanding of the financial and operating performance of our businesses than would not otherwise be achieved using IFRS results alone. CFe should be used as a supplemental measure and not in lieu of our financial results reported under IFRS.
